The web page that you point to summarizes it differently: - Tier 1 is "guaranteed to work". - Tier 2 is "guaranteed to build" and "often works". - Tier 3 is best effort. And that is not very different from Gnulib's target platform policies [1]. arm-linux-androideabi, i686-unknown-haiku, powerpc64-ibm-aix, m68k-unknown-linux-gnu are also "best effort" for Gnulib. Therefore the list of platform support is not deterring me from Rust. Bruno [1] https://www.gnu.org/software/gnulib/manual/html_node/Target-Platforms.html
